Okay, Vassili has been upgraded in my book from "highly-competent" to "genius". I cut a block of basswood at 15 degrees as he specified. I ran my Tosagata santoku through the gamut of coarse DMT DiaSharp and 500, 1000, and 2000 grit Shapton GlassStones. I finished up with my chromium oxide-loaded strop, and whittled a hair. Whittled a freakin' hair! Just like in the videos!
